Application le November 3 To all whom it may concern:

lie it known that we, FRANK M. Ennemis and RUSSELL J'. GoonNow, both of Boston,` in the county of Sutiolk and State of Massa- 5 chusett-s, citizens of the Unit-ed States. have invented a new and useful Improvement in Gasolene-Measuring Rules, of which. following is -a specification.

Our invention is intended for' use in measuring the amount oic gasolene or other liquid in a tank and is especially intended for use with the gasolene tank' of an auto mobile. Such tanks are irregulacminishape so thatJ the increase or decrease in' the depth of the gasolene does not necessarily show the number oi gallons which have been added to the contents or have. been used. It is very common to determine in a general way whether a tank contains gasolene enough for a given trip by taking a stick and measuring the depth of the gasolene and guessing to whether there is gasolene enough .in the tank or not. The practical ditlieulty with this is that one is apt to rely on onels memorynnd at the critical timethe beginning of the return trip-forget the depth ot gasolene at the beginning of the trip, so that the measurement by a stick is ineffective.

Uur invention is intended to provide on the one measure an indication of the depth of the tank, gallon by gallon, and also to provide an indication of the depth at any particular time, and our invent-ion will be understood by reference to the drawings, in

which-- Figure 1 represents the preferred form of our invention, Fig. 2 being a side view and Fig. 3 beingl a section on line 3-3 of Fig.

it@ 1. Fig. et shows one modification in cross section. Figs. and ti are side and back views, respectively, of another modiiication ot our invention. Fig. 7 is a section on the line 7W?, Fig.

in. Figs. 1,2, 5 and 6 portions only of the measure are shown to indicate that the measure may be of any desired length.

Enough, however, of each form of measure shown is given to indicate the principle on 0 which it is constructed.

Turning to the form oi? our rinvention shown in Figs. l, Q and 3, A is a measure which is preferably made ot' wood out may` be of metal or other material unatlccted by gasolene -or the liquidv to be measured. In

cross section, as seen in Fig. il, it. is shown that the measure is provided witha channel B and a slot C both of vwhich run the full length of the measure and connect with each other. In the slot and channel B run pointers D. Each pointer (of which there are a number corresponding to the number of gallons or other units to be measured by the rod) consists of a plate (l having` a short screw pin Z1 which projects through the slot A pointer E provided with a suitable hole to lit over the screw pin (Zlhrests on the top of the measure A under the thumb nut QC. The pointer E may therefore be broughtJ to any point alon'g the line ofthe slot and there clamped hyl the thumb nut d2. In addition to these features we'also provide a marker F which does not necessarily have a clamp screw, being in fact preferably slidable along the measure but clamping the measure sufficiently tightly to require considerable strength to move it.

Each measure is intended to be used with its own tank, that is to say, a person having more than one tank will have an equal number ot' measures, and to use the measure in the manner in which we intend he pours into his empty tank a gallon or other unit of liquid and puts hisl measure through the inlet opening and rests it on the bottom of the tank. 0n withdrawing theineasure the liquid will leave its mark thereon aiid so indicate the depth of one gallon of liquid in the tank. He will then set and clamp the first pointer 1 at that point. .lle then pours in another gallon of liquid and repeats the operation, using this time the second pointer 2, and so on until his tank is full. The pointers all being thus clamped in place serv -as a measure on all occasions for-the'contehts of that particular tank.

lt is well known that a gasolene tank of an automobile is sometimes concave in the bottom or convex or irregularin shape as to its vertical walls or otherwise irregular in shape, so that it is not unusual when the operation is finished to find onesfmeasure yarranged somewhat as shown in Fig. l where the distance vfrom the pointer 1 to the bottom of the measure indicates the depth of one gallon. From 2 to the bottom of the measure indicates two gallons although the distance between 1 and 2 is less than the dstance` of. 1 toV the bottom of the measure.

rlhe pointer 3 inthe same Way indicates three gallons and 4 four gallons, ete., these 'Y marker F at that point and thus has a recl Way as in Fig. 1.

to leave 'a slot C1 va'ndallow the sliding of' 0rd that he had siX gallons when he started for there his marker F remains until he changes it. After he has ridden a certain number of hours and realizes that he has perha s an hour more to ride before Areaching his destination arid that his gasolene must be getting low, he drops his measure into the tahk as before and finds that he has' one gallon left. In other Words, he has used five gallons during the period of time in which lhe has been riding. He can then judge Whether he has gasolene enough to take him to his destination Without relying -bn his memory.

In the form of our invention Shown in Fig. 4 the general structure is the saine eX- cept that in this vcase the channel B1 is some- Whatdeeper than in the form shown in Fig. 3 and the plate d10 is a spring plate, this makving it a little more ditiicult to adjust the marker F -a'lthough'it is done in the same vn the form 'of our inyention shown in Figs. 5, 6 and 7 the measure comprises two parts A1, A2. The portion A1 is provided with a flange A3 lin each side, ormin a recess A5 in which slides the pointer 1.

'The part A2 is attacheil at each end to a projection A4 at eachendf the part A1 so as Les the pointers E1' and yet nserve as a protecaccidentally. `A .slot isthus formed at G1 through which the ointers may be slid. to their required position. These pointers are used in the same way as the pointers in Y Fig. .1, Abut they rely upon their protected condition between the iiange A3 'and the piece A2 and their own shape to keep their. in place. A marker F is also lprovided like that'shown in the other figures, which, however, slides around the entire outside et the tion may be embodied but those shown are very simple and economical to make. The marker F may be omitted if thought best.

Vhat We claim as our invention is I tion to them so that they will not be moved i The measure above described comprising FRANK M. entremos. RUSSELL J. GOODNW.
